Development project

Water and Resource Recovery Facility (VARGA)

Envidan (alongside BIOFOS and other partners) has been granted more than 19 million DKK for a lighthouse project called VARGA. The allocation comes from the Danish Ministry of Environment and Food as part of the MUDP programme. The project is meant to ensure that resources in wastewater and waste are utilized even better than today which will ultimately benefit the Danish citizens.

The main purpose of the project is to transform a traditional wastewater treatment facility into a Water & Resource Recovery facility. The project develops essential parts of the circular economy focusing on achieving CO2 neutrality as well as utilizing the nutrients in urban waste and wastewater in the production of organic food. Thus, the project demonstrates synergies through cooperation on the exploitation of resources across water, waste, and organic agricultural sectors.

The way to the future of wastewater treatment facilities

The project outlines the visionary goals of the future wastewater treatment facility. The conventional wastewater treatment facility must be rethought as a resource facility that both treats wastewater and utilizes the resources to the fullest. This will be demonstrated at one of Denmark's largest wastewater treatment facilities, Avedøre (capacity of approx. 400,000 PE) as a case Danish environmental technology in an international context.

Interdisciplinary efforts

Envidan, BIOFOS, ARC, UNISENSE and DTU Miljø are all partners on the project, and together they aspire to find new methods for achieving CO2 neutrality and utilization of resources in VARGA.

"We see great prospects in terms of export in the Lighthouse project VARGA within our consulting services such as CO2 neutral purification, circular economy, upgrading biogas, advanced online management as well as deliveries of Salsne's filters for optimizing carbon harvesting and concentrating primary sludge," says Development Manager at Envidan A/S, Jeanette Agertved Madsen.

It is not the first time Envidan has worked with BIOFOS. Besides VARGA, they are also working on a 2025 expansion strategy for all three wastewater treatment facilities in BIOFOS as well as an expansion of digester capacity, new sludge storage and reconstruction of sand trap at the local wastewater treatment facility Lynetten.
